Problems solved by technology

However, when running a node of the POS chain, it is usually required that the node has a high online rate, and at the same time, it is not possible to repeatedly sign "the same block height and the same type of content", otherwise there will be economic losses

Embodiment Construction

[0020] Such as Figure 1-5 As shown, in the embodiment of this application, the block chain mechanism is introduced first, please refer to figure 1 , figure 1 It is a schematic diagram of the decentralized distributed data record in the embodiment of the present application. As shown in the figure, the blockchain (BlockChain) can be considered as a distributed data record account with a decentralized distributed data record method. By maintaining the chain structure of data blocks, continuously growing, shareable and non-tamperable data records can be maintained. Whether it is a terminal device, a server or a cloud server, it can participate in the data recording, and the data recorded on the blockchain cannot be deleted or tampered with. Blockchain technology mainly allows any number of nodes participating in the system to associate a series of data blocks (blocks) generated by cryptographic methods. Each data block contains all information exchange data of the system withi...

Abstract

The invention discloses a block chain signature processing method based on a POS consensus mechanism. The key server obtains the first data to be processed of the first block chain node, and the key server sends the first data to be processed to the signature server. The first target data, so that the signature server uses the private key to sign the first target data; the key server receives the signature information sent by the signature server; the private key of the signature server is stored in the hardware wallet, and the signature server needs to The required private key can only be obtained through the hardware signature of the hardware wallet; the benefit of this application is that it provides a method that can separate the private key from the node and manage it separately, and can avoid multiple signature requests of "same height and same type". A blockchain signature processing method based on the POS consensus mechanism of secondary signatures.

Description

technical field [0001] The invention belongs to the field of block chains, in particular to a method for processing block chain signatures based on a POS consensus mechanism. Background technique [0002] As an emerging technology, blockchain is still continuing to evolve while achieving certain success. The consensus mechanism of the current blockchain has gradually transitioned from POW (proof of work) to POS. At present, many POS chains have been launched and successfully operated, bringing features including decentralization while saving a lot of energy consumption. However, when running a node of the POS chain, it is usually required that the node has a high online rate, and at the same time, it is not possible to repeatedly sign "the same block height and the same type of content", otherwise there will be economic losses. This puts forward certain technical requirements for node operators. Contents of the invention [0003] The purpose of the present invention is t...
